Is this a 2x 512MB kit? If so, I think you could get a more well known brand. I've never heard of PQI. Something like Mushkin, OCZ, Kingston, G.Skill, or Corsair would be a better choice. That price is nothing too special. For a marginal amount more you could get a more well known brand that will probably perform better.

Someone else want to come in and correct me? This is my first time hearing the PQI name.
